Methods for manufacturing pixel unit, liquid crystal display panel, and electro-optical apparatus

A method for manufacturing a pixel unit, comprising:

• providing a semi-finished pixel unit having a display area, and the pixel unit comprises:
• a first substrate;
• a second substrate disposed in parallel to the first substrate;
• a liquid crystal layer disposed between the first substrate and the second substrate;
• at least one UV absorption pattern disposed between the first substrate and the second substrate, wherein a part of the display area overlaps the UV absorption pattern to define at least one first alignment area, and the part of the display area which does not overlap the UV absorption pattern defines at least one second alignment area;
• and
• providing an UV light, wherein the UV light irradiates the liquid crystal layer from a side of the UV absorption pattern away from the liquid crystal layer so that the liquid crystal molecules of the liquid crystal layer present different pre-tilt angles in the first alignment area and the second alignment area.
